__NOTOC__
The name PVC pumps covers a large number of different hand pump designs, which have in common that most parts are constructed out of PVC. PVC is used because it is often cheap, and easy to work with. As PVC is less durable as other materials such as steel, a single PVC pump should be used by a limited number of people. Because of the low price, PVC pumps are often used as family pumps. Sometimes other types of Plastic are used, such as ABS, which is UV resistant.

An important issue with all PVC pumps is the tendency of PVC to become brittle when exposed to direct sunlight for some time. Some pumps, such as the Baptist and EMAS pump, solve this by having a concrete pillar around the PVC tube, and by constructing the handle part out of galvanised steel pipe. Other pumps, such as the Canzee pump, use the UV-resistant plastic ABS. The negative effects of sunlight can be partly avoided by shielding the pump from direct sunlight, by painting PVC parts, or by protecting the PVC in some other way. In Bolivia, a strip of cloth is wound around the PVC parts, and held together with a piece of metal wire.
